Regular or high test gasoline
I have a 24' motor home with a Ford V10 gas engine. Was wondering if anyone has gave it an honest test for gas mileage using high test vs regular. Is it worth the money difference ?

Motor calls for "regular" (87 octane) that's all it needs. Getting "premium" (92 octane), IMO, you're just throwing money away. As far as pinging goes,,,the computer takes care of that in a nano-second...by retarding the timing until it no longer "senses" a problem.
